Abstract

The article describes the magnetite dissolution kinetics in the modeling environment depending on the time of dissolution and pH. The results of solubility by spectrophotometry, atomic absorption and gravimetric methods are given. It is revealed that the magnetite is better soluble in an acidic medium with a decrease in acidity and in alkaline environment magnetite is more soluble at higher pH. It is revealed that the magnetite solubility increases with increasing time of incubation. The order of reaction (I-st order) and rate constant of magnetite dissolution are determined. The optimum concentration of the starting materials and conditions of the magnetite synthesis are matched. It is found that the magnetite is able to dissolve in the model environments and can be used for delivery of the iron (II) into the body.
